The shiny new Nexus 7 may be the current king of the 7-inch jungle, but that doesn't mean you should pass up a good deal. The Kindle Fire HD - that's the upgraded 720p tablet, not the newer non-HD Fire - is $40 off for all models at the moment. The Amazon storefront shows "For a Limited Time," so we have no idea how long this price will last.

The price drop applies to all the variations of the 7-inch Kindle Fire HD. That makes the base 16GB WiFi model with "special offers" (integrated Amazon advertising) $159, the same price as the non-HD Fire, which is not on sale. You can bump it up to 32GB for $189. Without Amazon advertising, the tablets go for $174 and $204, respectively. (Add the tablet to your shopping cart to see storage/advertising options.) According to price-checker CamelCamelCamel, this price is as low as it's ever been.

Considering both the hardware and software limitations of Amazon's tablets, even that price drop will make it a hard sell to serious Android users. But if you're looking for a nice gift or you're already heavily invested into Amazon's media marketplace, it might be a good deal - remember that Amazon still steadfastly refuses to give Google-equipped Android devices access to its streaming videos. Even though there's an Amazon Video app for iOS. And Google TV. (Seriously, Amazon, cut the crap and let me watch Prime videos on my phone.)

If you're tempted by the offer, you'd best move quickly. If the the deal is limited by stock, it may disappear soon.
